Natural convector
Illustrated Guide to Mechanical Building Services 3rd Edition (BG 31/2017), written by David Bleicher and published by BSRIA in May 2017, suggests that natural convectors: ‘…generally consist of a casing with top and bottom openings, and a finned hot water pipe at low level. The hot water pipe creates an upward convection current of hot air within the casing, pulling room air in at the bottom and pushing hot air out at the top. Some units incorporate a damper to regulate output. Low level convectors are also available which are ideal for placing below full-height windows to counter cold downdraughts. A similar type of unit can also be placed in a trench below the window, leaving only the top grille visible. The main benefit of convectors in comparison to radiators is their greater heat output per unit size and their quicker warm up time.’
